4 Claims.

This application is a division from my copending parent case Serial No. 287,221, filed July 29, 1939, Patent No1 2,330,737, dated September 28, 1943, and the invention herein relates more particularly to the means for assembling the stock, receiver, and trigger guard of the rifle shown in said parent case.

In the drawings,

Fig. 1 is a longitudinal section through the receiver and part of the stock and barrel of the rifle of the present invention, the bolt and much of the interior mechanism of the rifle mounted on these parts being removed for better illustration;

Fig. 2 is a top view of the receiver;

Fig. 3 is a right side view of the guard assembled to the receiver, the intervening stock being omitted;

Fig. 4 is a section through the receiver, anchor, and guard, on section 4--4 of Fig 3;

Fig. 5 is a section through a portion of the guard and the receiver on section line 5--5 of Fig. 3;

' Fig. 6 is a section through a portion of the guard and the receiver on line 6 6 of Fig. 3; and

i Fig. 7 is a fragmentary section on line 1-1 of Fig. 1 on a slightly smaller scale, showing the stock as embraced by the receiver and guard.

Referring to Figs. l, 2, and 3, the receiver on the rifle is indicated at the barrel 2, stock 46, and the trigger guard |0|. The shape of the receiver is shown clearly in Figs. 2 and 3 and its forward end is formed with a well-like passage 4 therethrough constituting the magazine chamber adapted to receive a clip of cartridges (not shown). The barrel 2 is screw threaded into the receiver as indicated at 2a.

The stock 46 of the rifle is of the usual wood formation and is only partially shown in the present case in section, reference being had to applicants copending case for disclosure of the complete stock. This stock 46 is embraced or claniped in a specialA manner as hereafter described between the receiver I which is on the upper side of the stock, and the trigger guard ||l| which is on the lower side of the stock.

As shown in Fig. 1, anchor 50 is seated in a transverse slot 89 of the stock 45. The anchor screw 90 drawing against the anchor nut 9| secures the anchor firmly to the stock. The an chor carries a transverse slot 92 which ts the recoil lugs 93, 94 of the receiver and holds the receiver against recoil or end movement with respect to the stock. (Figs. 3 and 4.)

The head 95 of the anchor screw 9|l draws against the bottom of the anchor slot 92. The lower faces 96, 91 of the receiver recoil lugs 93 and 94 bear against the same surface of the anchor slot. As the underhead length of the anchor screw may be accurately fabricated it follows that the distance from the faces 96, 91 of the receiver recoil lugs 93, 94 to the lower end 93 of the anchor screw is constant (when the stock is firmly clamped between the anchor 50 and the anchor nut 9|), regardless of the expansion or shrinkage of the wooden stock. As the lower end 98 of the anchor screw forms a stop for the rear end of the guard, Figs. 1 and 4, a spacer of constant length is thereby provided as between the rear ends of the receiver and of the guard. This arrangement enables the detachable guard to be assembled to the receiver with uniform precision regardless of expansion or shrinkage of the wooden stock.

The receiver is provided with a transverse groove 99 near its front end, into which the tenon |09 of the guard |0| engages as in Fig. 3. The receiver also carries a pair of ribs |02, |03 which project downwardly between the side wall shoulders |94, |05 of the guard |0| to hold the guard in correct lateral alignment with the receiver, Fig. 6. The receiver is fonmed with a pair of sockets |06, |01, Figs. 3 and 5, which open downwardly and rearwardly. Two trunnions or laterally lprojecting pins HIJ, ||0a on rear vertical extensions lll, |09 of the guard engage in the sockets |06, |01, to accurately position the guard with respect to the receiver. The length of the anchor screw is such that the rear end of the guard abuts the end 98 of the anchor screw just before the guard trunnions ||0, |||la are moved upward to their seats in the receiver sockets |06, |01. When the trunnions are moved upward to their seats, the rear end of the guard, having a limited ilexibility, is sprung slightly with respect to the remainder of the guard. As the trunnions IIU, IIUa are moved upward to their seats in the receiver sockets |06, |01, the guard tenon Ill, having previously been entered into the receiver groove 99 is moved forward to full engagement with the receiver groove, due to the forwardly inclined path of the guard trunnions as controlled by a pair of cam surfaces such as l, which lead into the sockets |66, Ill'l, Fig. 3. When the guard trunnions llll, ||Ua are moved downwardly out of the receiver sockets |86, |01, the guard at the same time is moved toward the rear, as controlled by the cam surface ||2 which is an integral part of the guard wall |08 riding on the inclined cam surface H3 formed on a web of the receiver, see Fig. 1, thus withdrawing the tenon, from the receiverv The rear end of the guard is posigroove 99. tioned laterally in the receiver by having its rear vertical extensions |08, |09 engaged between the receiver side walls H4, H as shown in Figs. 3 and 5. l

A latch hook H6, Fig. l, for retaining the guard in place, is detachably carried on the hook pin H1, which is pivotally mounted between the side walls H8, H9 of the guard. The face |20 of the latch hook engages over the notch shoulder |2| of the receiver, Fig. 1, to hold the guard rmly upward in the receiver. The hookface is a slow cam with draw suflicient to tighten the guard to the receiver `despite .small variations as between the affected surfaces. The latch hook is provided with a slot |22 occupied by the key |23 integrally formed on the hook pin Hl so that the latch hook may be rocked by means of the outside handle |24 on the hook pin |I|`|.` Fig. Seshows ,in solid lines the handle |24 in the position oi the latch hook engaged with the notch shoulder |2| of the receiver, and the handle (dotted) in the position of the latch hook disengaged iromthe shoulder |2| of the receiver preparatory to detaching the guard from the receiver. l

The latch hook is provided with an incline |3| which is ridden dow-n by the incline |32 of the receiver, when the guard is being assembled to the receiver. One end |33 of `a double ended spring |34 engages a notch seat |30 in latch hook H6 and constantly forces the hookinto engagement Vwith the notch shoulder |2| of the receiver, Fig. 1.

The tenon |00 of vthe guard, engaged in the slot :99` of the receiver,'iorms a fulcrum around which the guard swings .as its rearward end is assembled upward into the receiver. Ihis swinging of the guard provides a leverage to compress the stock shoulders |35, ld between the receiver shoulders |31 and the guard shoulders |38, see Fig. 7. y

I claim:
